Stomata open when guard cells swell due to

Identify the correct statements and find out the correct combination ? 1. Accumulation of K^(+) ions in guard cells does not require energy 2. A high pH favours stomatal opening 3. Movemant of chloride ions into guard cells is in response to electrical differential created by K^(+) ions 4. With entry of several K^(+) ions and chloride ions, water potential of guard cells increases .

Stomata open when guard cells have:

During the opening of stomata , the organic malate ions are produced in the guard cells for maintaining the

Consider the following events involved in stomatal opening 1. Turgor pressure of guard cells increases 2. K^(+) ions move into guard cells 3. Formation of malic acid 4. Water moves into guard cells What is the correct sequence of these events leading to opening of stomata ?

Stomata generally open during the day because the guard cells have

Rate law for the reaction A+2BrarrC , is found to be Rate =k [A][B] . Concentration of reactant 'B' is doubled keeping the concentration of 'A' constant , the value of rate constant will be-

Select the correct events leading to the opening of the stomata (i) Decline in guard cell solutes (ii) Lowering of osmotic potential of guard cells (iii) Rise in potassium levels in guard cells (iv) Movement of water from neighbouring cells into guard cells (v) Guard cells becoming flaccid

The hormones which help in the intake of K^(+) ions by guard cells and hence speed up the opening of stomata are
